AKT1 and posterior cortical atrophy: The results demonstrated that CFF‐1 treatment in PCa cells greatly decreased the levels of phospho‐AKT (p‐AKT, including Ser473 and Thr308 sites) and phospho‐PI3K (p‐PI3K) and their activities, while no obvious changes on total AKT and PI3K protein levels; and the decreasing degrees of p‐AKT and p‐PI3K levels presented in a CFF‐1 concentration‐dependent manner (Fig. 3A and B).
